14 CFR Part 39

[Docket No. FAA-2013-0666; Directorate Identifier 2013-NM-060-AD; 
Amendment 39-17635; AD 2013-22-03]
RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all The 
Boeing Company Model 727 airplanes. This AD was prompted by reports 
indicating that a standard fuel tank access door was located where an 
impact-resistant access door was required, and stencils were missing 
from some impact-resistant access doors. This AD requires an inspection 
of the left- and right-hand wing fuel tank access doors to determine 
that impact-resistant access doors are installed in the correct 
locations, and to replace any door with an impact-resistant access door 
if necessary. This AD also requires an inspection for stencils and 
index markers on impact-resistant access doors, and application of new 
stencils or index markers if necessary. This AD also requires revising 
the maintenance program to incorporate changes to the airworthiness 
limitations section. We are issuing this AD to prevent foreign object 
penetration of the fuel tank, which could cause a fuel leak near an 
ignition source (e.g., hot brakes), consequently leading to a fuel-fed 
fire.

DATES: This AD is effective December 5, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 5, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM published in the Federal Register on August 1, 2013 (78 FR 46538). 
The NPRM proposed to require an inspection of the left- and right-hand 
wing fuel tank access doors to determine that impact-resistant access 
doors are installed in the correct locations, and to replace any door 
with an impact-resistant access door if necessary. The NPRM also 
proposed to require an inspection for stencils and index markers on 
impact-resistant access doors, and application of new stencils or index 
markers if necessary. The NPRM also proposed to require revising the 
maintenance program to incorporate changes to the airworthiness 
limitations section.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received. The Boeing Company 
supported the NPRM (78 FR 46538, August 1, 2013).

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed--except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 46538, August 1, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 46538, August 1, 2013).

Costs of Compliance

    We estimate that this AD affects 139 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                       Cost per    Cost on U.S.

                                            = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need these 
replacements:

                                                 hour = $170.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
